Chapter 7, Problem 7.53AP

Interpretation Introduction

Interpretation:

K for the given reaction at ${25}^{0}C$ has to be determined. The given reaction is whether reactants or products favored has to be determined.

Concept Introduction:

Equilibrium constant: It is the ratio of products to reactants has a constant value when the reaction is in equilibrium at a certain temperature. And it is represented by the letter K.

For a reaction,

$\text{aA}\text{+}\text{bB}\rightleftarrows \text{cC}\text{+}\text{dD}$

The equilibrium constant is, $K=\frac{{\text{[C]}}^{\text{c}}{\text{[D]}}^{\text{d}}}{{\text{[A]}}^{\text{a}}{\text{[B]}}^{\text{b}}}$

Where,

a, b, c and d are the stoichiometric coefficients of reactant and product in the reactions.

If $K<1$, then it is reactant favoured reaction whereas if $K>1$, then it is product favoured reaction.
